In private houses, cottages and dachas, where there is no centralized gas pipeline, gas stoves are used for bottled gas. Cylinders are filled with propane-butane liquefied mixture. Natural gas (methane) cannot be converted to a liquid state at room temperature. A gas stove with a cylinder is allowed for installation in a building with no more than two floors. No more than one device per home is allowed. Vessels must comply with the intended purpose, established standards and be verified at the gas company.
Equipment placement
To avoid problems with gas leakage during use, the bottled gas stove must be properly connected to the source. It is better to install the cylinder on the street, but it must be taken into account that in frosty weather the gas does not evaporate well, and the stove stops working normally. When installed outside the building, the cylinder should be located no closer than 0.5 m from windows and 1.0 m from doors. If basements and basements are located nearby, the distance from the entrances to them is maintained at least 3 m. The container must be protected from heating above 45 ° C and mechanical damage. To place the balloonuse special cabinets.
The cylinder, installed in an outdoor cabinet, is connected to a steel pipe laid along the outer wall, at a height of at least 2.2 m from the ground level. Inside the building, a flexible hose is mounted to the pipe through a shut-off valve and is connected directly to the stove. Gas stoves for bottled gas are installed at a distance of at least 0.5 m from the vessel (with the exception of built-in ones) and at least 1 m from heating devices. When equipping a protective screen made of non-combustible materials that protects against thermal effects, an interval of 0.5 m is allowed. The volume of the room where the equipment is installed should be from 8 to 15 m3.
Connecting devices
The gas pressure in the cylinder can have different values. A certain pressure must be applied to the nozzles of the plate - 0.3 MPa. To reduce it when a combustible mixture enters, a reducer is used. It has a left-hand thread and is screwed in only with an open-end wrench so as not to cause a spark. FUM tape, flax with paste, paronite gaskets are used as sealing materials. Gas stoves for bottled gas, when properly connected, should produce an even flame with a blue tint. The diameter of the jets in the nozzles of such equipment should be 0.89–0.93 mm.
To connect it is strictly forbidden to use hoses that are not intended for use in a gas system - water, hydraulic, oxygen, etc. Fittings are also mounted only for gas purposes. They aremust have a conical seal and a landing mirror. Before buying a flexible hose, pay attention to the size of the thread at the inlet to the stove. You may need an adapter, usually included with the stove. Also consider the shape of the inlet pipe. It can be straight and angular. For a straight line, you need a hose with a square at the end. Connection length - no more than 1.5 m. If a hose without connecting elements is used, a fitting is wound onto the inlet pipe using winding. It may be included with the plate. In this case, the hose is connected to the fitting and to the outlet of the reducer using clamps.
The mounted hose, reducer and connections must be accessible for inspection. After installation, the tightness of the connections is checked using soap suds. When opening the container, it should not bubble. If leaks occur, shut off gas and replace gaskets or tighten clamps.
Portable gas stove is equipped with an insert disposable collet cylinder. But some models have the ability to connect larger vessels using an adapter.
Cylinder gas stoves should not be installed in rooms with a cellar, underfloor, or near other rooms with a lower level. The propane-butane mixture is much heavier than air and tends to accumulate in unventilated enclosed spaces. If a high concentration is reached and a spark or open flame is present, an explosion may occur. The rules for installing equipment are informative. For mounting devicesit is necessary to contact the specialists of the gas services.
